Abstract

In a tunnel-WLAN model of a UMTS/WLAN interworking system, a user always prefers to access the WLAN as soon as he/she moves to a WLAN hotspot. Thus a user never misses the higher bit rate of WLAN as long as its bandwidth is available. We have examined that overall dropping probability of a request in a mixed cell (i.e., a UMTS cell with underlying WLANs) improves if and only if the blocking probability of a request in WLAN remains lower than that in the UMTS system. Thus dropping probability increases with increasing blocking probability in WLAN. We propose a WLAN-first access scheme which transfers all blocked requests of WLAN to overlaying UMTS system, thereby preventing compulsory dropping of blocked requests in WLAN. This technique improves the request dropping probability in an entire mixed cell.
